Arsenal manager Unai Emery is hopeful the club will bring in reinforcements during the January transfer window
Emery, however, declined to say whether Denis Suarez will be one of them.
The Barcelona midfielder has been heavily linked with a move to the Emirates to reunite with Emery, who he worked with at Sevilla.
After the 3-0 FA Cup third-round win over Blackpool, Emery said: “I think the club is working for the possibility to take some players who can help us during these next four months.
“Maybe the transfer market can help us with a centre-back, but it is not easy because also (Konstantinos) Mavropanos is coming back after injury. Also a winger, right or left, one player can help us in this position.”
Asked whether he saw Suarez as a winger, the Gunners boss added: “He was playing in his career, and with me also, as a right or left winger.”
Emery suffered another defensive headache in the warm-up at Bloomfield Road when Lauren Koscielny felt his back tighten and was replaced in the starting line-up by Carl Jenkinson.
The Arsenal manager is optimistic it is not a big issue, though, saying: “I hope he’s going to be OK for the next matches.”
